Title: Image forming device provided with automatic document feeder
Inventor: ISHIBASHI TOSHIHIRO
IPC: B65H31/00
Filed: 1990-09-28
Abstract: PURPOSE:To prevent a document from being left ejected because a document receiver is forgot being set by providing the document receiver at a middle stage on the side of a main body. CONSTITUTION:The CF document receiver 21 is provided at the middle stage on the side of the copying machine main body 10 and the set state of the receiver 21 is easily brought into the sight (visual field) of an operator. Even though the operator starts copying while he forgets the setting operation of the receiver 21, for example, he is aware of forgetting the setting of the receiver 21 when the leading edge of the CF document is carried to a paper ejection tray 15. This is because the folded CF document on the receiver 21 is brought into the visual field in the case that the receiver 21 is regularly set. Therefore, a situation that the operator is not aware of forgetting the setting of the receiver 21 until many CF documents are accumulated on a floor surface as in the conventional manner is prevented, so that CF document is prevented from being left ejected because the receiver 21 is forgot being set before it occurs.

IPC: G01F1/84
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To form a conduit with a relatively small mass by allowing electric current to flow through the conduit or a fluid medium at least partially. SOLUTION: Both ends of a conduit 1 are short-circuited from a measurement casing 6 via grounding. Current flowing through the conduit 1 is connected to the conduit 1 via ring transformers 7 and 8, and the conduit 1 forms a part of the secondary coil winding of the transformers 7 and 8. Therefore, the level of current flowing through the conduit 1 is an AC current obtained from the sum of (each current) × (number of turns) of the transformers 7 and 8. A magnetic field formed by the AC current vibrates the conduit 1 by the mutual action with the external magnetic field of a magnet 9. The magnet 9 may be either a permanent magnet or an electromagnet, thus excitation can be done without any contact, and detection of the movement of the conduit 1 is made possible without providing an additional device.
